If the points are arranged on an imaginary line with one line connecting each point to its neighbor, there will be 99 lines (or line segments).
100*99/2 = 4950
There are 91 lines.
there are 6 lines can pass through 4 noncollinear points.
There are 20 common points.
points : infinite lines : 4 vertices : 4
the parallel lines never intercept so they do not have any common points.
3 points
If no pair of lines is parallel and if each pairwise intersection is distinct, there will be 499500 points of intersection.

you have to make four or five horizontal lines in order to get 100 points.

In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary. Even in the Euclidean plane, two points determine infinitely many lines that are not straight!

In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.
